Title: Indazole derivatives
Inventor: DAVIES ROBERT RONALD
IPC: C07D231/56
Filed: 1953-10-23
Abstract: The invention comprises hydroxyindazole sulphonic acids wherein the hydroxyl group and the sulphonic acid group are the sole substituents attached to the benzene ring of the indazole nucleus.  Such compounds are obtained by heating the corresponding aminoindazole-sulphonic acid with water or dilute mineral acid under pressure at a temperature between 150 DEG  and 210 DEG  C.  The products are useful as coupling components for azo dyes.  The starting materials may be obtained by sulphonating the appropriate aminoindazole, heating the appropriate aminoindazole sulphate or by diazotizing the appropriate nitro-o-toluidine sulphonic acid, ring closing and then reducing the nitro group to an amino group.  In examples: (1) 6-hydroxyindazole-4-sulphonic acid and 5-hydroxy-indazole-7-sulphonic acid, (2) 5-and 6-hydroxyindazole-5-sulphonic acids and (3) 4 - hydroxyindazole - 6 - sulphonic acid are prepared by the above methods, (1) and (3) in sulphuric acid medium and (2) in medium faintly acid to litmus.  The products are converted to p-chloro-benzyl-isothiouronium derivatives.  6 - Amino - indazole - 4 - sulphonic acid is prepared by the sulphonation with alum of 6-aminoindazole.  6-Amino-indazole-5-sulphonic acid is prepared by heating 6-aminoindazole sulphate with sulphuric acid in boiling o-dichlorobenzene, with the continuous removal of water. 4-Amino-indazole-6-sulphonic acid is prepared by diazotization of 6-nitro-o-toluidine-4-sulphonic acid, ring closure, and subsequent reduction of the nitro group.  Specification 697,977 is referred to.ALSO:Hydroxyindazole sulphonic acids wherein the hydroxyl group and the sulphonic acid group are the sole substituents attached to the benzene nucleus (see Group IV(b)) are useful as coupling components in the manufacture of azo dyestuffs.

Patent GB-746390-A (GB)
Title: Improvements in or relating to hydraulic presses having at least two press cylinders
IPC: B30B15/24
Filed: 1953-10-23
Abstract: 746,390. Hydraulic presses. AKT.-GES. C. ZSCHOKKE ZWEIGNIEDERLASSUNG DOTTINGEN. Oct. 23, 1953 [Oct: 24, 1952], No. 29416/53. Class 69 (2). A hydraulic press having at least two cylinders, each of which transmits pressing forces to a point of attack on a common press beam, is provided with means controlling the admission and exhaust of liquid to and from the cylinders so as to ensure parallel motion of the press beam. Cylinders 4 with double-acting pistons 5 acting on a press beam 3 are supplied with liquid from a pump 11. The pump supplies liquid through a pipe 13, in which a main valve 15 is situated, to pipes 16. A valve 17 is associated with each cylinder 4 and controls the admission of fluid from a pipe 16 to either end of the cylinder. Valve pistons 32 of the valves 17 are interconnected through racks 40, pinions 42 and a shaft 41 rotatably mounted on the beam 3. Depression of a hand lever 25 or foot lever 26 raises the piston 29 of the main valve 15 to put the pipes 16 into communication with the pump, and also, through springs 44 and an arm 43, raises the valve pistons 32 so that an upper chamber 6 of each cylinder 4 communicates with a pressure pipe 16, and a lower chamber 7 communicates with a relief pipe 19. The press beam is thereby moved towards the table 1. Should, for example, the left hand end of the beam move slightly ahead of the right hand end, the shaft 41 is correspondingly inclined. The right hand rack 40 is prevented from moving upwardly due to the piston 32 abutting against a valve cover 36. The left hand rack is therefore moved downwardly, entirely or partly closing the control ports communicating with the upper and lower chambers of the associated cylinder 4. The corresponding piston 5 is thus halted or moved slowly until the other end of the beam has caught up. If the levers 25, 26 are put in their intermediate position the valve pistons 32 assume the position shown, in which the chambers 6, 7 of the cylinders are closed and the press beam is maintained in the position it happens to occupy. To open the press, lever 25 or 26 is raised. Valve 15 again puts pipes 16 into communication with the pump, and pistons 32 are lowered, putting the chambers 7 into communication with the pressure pipes 16, and chambers 6 into communication with the relief pipe 19. Parallel motion of the press beam is again ensured during its rising motion, move ment of the control piston at the lagging end being prevented by the bottom cover 37 of the corresponding valve.

BOBY, Ltd., R., St. Andrews Ironworks, Bury St. Edmunds, Suffolk.-(Assignees of Soenens, M. ; 1c, Boulevard de Smets de Naeyer, Courtrai, Belgium.) Oct. 6, 1930, No. 29889. Convention date, March 20. Void [Published under Sect. 91 of the Acts]. [Class 120 (i).] Flax stalks, suspended by one end, are conveyed through a scutching, " combing " or like machine 3 by a single continuous belt 1, Figs. 1 and 2, which then grips them by the other end for conveyance through a second scutching unit 4. The belt 1 is driven by a pulley 6 and passes over free pulleys 5, 15, 16. The stalks 2 are fed from a table 24 under the toothed crowns 35, 35a of the pulley 5 on to a bar 25 and an angled member 26 which causes the ends 2a of the flax to bend vertically upwards. The stalks are gripped between the belt 1 and the member 26 and the parts 2a come into contact with a helicoidal plate 27, Figs. 1, 2, 3, and 5, which forces them on to the upper surface of the belt, while the parts 2b having reached the end of the bar 25 hang vertically. On entering the scutcher 3 the right-hand edge of the belt engages under a second angled member 28, Fig. 6, which tightens the grip on the flax while the depending part 2b is scutched. On leaving this scutcher the belt passes over the inclined pulley 15, then over the horizontal pulley 16 and thus at 1b passes vertically beneath the part 1a. Before the stalks are released from the ends of the angled members 26, 28 the depending ends 2b are gripped between the part lb of the belt 1 and an auxiliary belt 21, Fig. 7, moving over pulleys 20, 22 and as the ends 2a are released they fall into the vertical position in which they pass through the scutcher 4. The belts 1, 21 are twisted before entering the guides 30, 31 and after leaving the scutcher 4 the belt 21 separates from the belt 1 which is twisted further before passing over the pulley 6. The scutched flax collects on a bar 33.
